We compared nectar, pollen and resin loads of individual workers among colonies from six Trigona species in Sabah, Borneo. Individual bees rarely collected
1). While not bees' primary source of carbohydrates, pollen also contains starches and other carbohydrates (glucose, fructose, sucrose) (Firon et al., 2006; Nepi et al., 2010; Pacini et al., 2006) During the pollen packing process, foragers also add salivary secretions and nectar (...
In our colonies, only a subset of foragers collected pollen, and no bee exclusively foraged for pollen. A minority of very active bees (19% of the foragers) performed 50% of the colony's total foraging trips, contributing to both pollen and nectar collection. Foraging performance (amount ...
